           Summary: hush does not handle process groups properly with "&"
                    when job support is disabled
           Product: Busybox
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P5
         Component: Other
        AssignedTo: unassigned at busybox.net
        ReportedBy: vapier at gentoo.org
                CC: busybox-cvs at busybox.net
   Estimated Hours: 0.0


if we disable job support in hush and then do something like:
$ sleep 999 &

then if we ctrl+c the next process, all backgrounded jobs also get that ctrl+c
signal
$ ps uax | grep sleep
... sleep 999
$ sleep 30
^C
$ ps uax | grep sleep
<sleep 999 is dead now>

if we enable job support, the correct behavior is observed

i'm pretty sure this is because we put all of the process group management code
behind ENABLE_HUSH_JOB
